Pat the steak cubes dry with paper towels and season generously with salt and pepper. Let sit for about 10 minutes.

Heat olive oil in a skillet over medium-high heat. Sear the steak cubes for 2-3 minutes on each side until golden-brown. Remove and set aside.

In the same skillet, reduce heat and add unsalted butter. Once melted, add minced garlic and sauté until fragrant. Return the seared steak bites and toss them in the garlic butter.

In a saucepan, melt remaining butter and add a clove of minced garlic. Pour in heavy cream, stir, and bring to a gentle simmer. Gradually stir in freshly grated Parmesan cheese until smooth.

Serve the Garlic Butter Steak Bites on a platter, drizzle with creamy Parmesan sauce, and garnish with parsley.
